I ran the game with just these mods enabled:
My sub still implodes too early. Does anyone else experience this? By the way, here is the CFG file for the IXD2.
Is there some other file that overrides the CFG file? When using the Environmental 4.3 Mod, I removed game changing files like the Submarine folder, CFG folder, and Library folder from the mod. All that remains are the graphic files and the Scene.dat file.
